What does the following Laravel code do?
Route::get('/user', 'UserController@index');
This code defines a route that responds to HTTP GET requests at the /user URL. When a request is made to this URL, Laravel will execute the 'index' method of the 'UserController'.
What will be the output of the following Laravel code?
echo str_plural('car');
The output of this code will be 'cars'. The str_plural function is a Laravel helper function that converts a string to its plural form.
What does the following Laravel collection method do?
$collection = collect(['taylor', 'abigail', null])->filter();
This code creates a collection and removes any null values. The filter method in Laravel collections filters the collection by a given callback, removing any elements that do not pass a given truth test.
What does the following Laravel code do in terms of concurrency?
DB::transaction(function () {
 DB::table('users')->update(['votes' => 1]);
